Subframe conector replacement

as you can see weld are not so good and the cut out bits really need to be sorted ive already removed the breather line. i was looking at filling in the cut out bits but think that as these are not of the shelf connectors for the price of some more box section it would be quicker and easier to just replace and end up with nice welds.
just really comes down to the best way to go about it. hence thoughts of doing 1 at a time while on a 2 post hoist (easier access under car and to a welder )VS axle stands at home and renting welder dont mind either.
but surly if a 2 post hoist is supporting the car at the same points or close to as where axle stands would go the should sit the same ???? have to asume hoist has been put in level of course.


Sorry just noticed ph to computer has turned pics 90 degrees
